# IMP1

**Drop-in framework for mobile ZK proofs.**

Built with ICICLE, this mobile-first proving framework brings privacy-preserving zero-knowledge proofs directly to iOS and Android. It’s lightweight, open-source, and optimized for fast, client-side performance with minimal setup required. IMP1 is built on ICICLE-SNARK, an end-to-end prover powered by ICICLE.

> [!NOTE]
> Android support for arm64-v8a architecture only.

## ✨ Features

🔧 **ICICLE Engine Inside**  
  Accelerated proving, powered by ICICLE.

⚡ **Fastest mobile proving experience**  
Up to 3x faster than Rapidsnark

🔓 **Open-source (MIT license)**  
  Free to use, fork, and build upon.

📦 **Minimal dependencies**  
  Lightweight and easy to plug in.

📱 **Built for iOS and Android**  
  Seamless integration across both major platforms.  
  _⚠ Android support for arm64-v8a architecture only._

✅ **Mobile-optimized Groth16 prover**
An efficient implementation of Groth16, built for mobile devices.

🚀 **Parallel proof generation on iOS**
Generate multiple proofs simultaneously with configurable batch sizes for optimal performance.

## 🚀 Quickstart

### iOS

1. [Download the xcframework](https://github.com/ingonyama-zk/imp1/releases/download/v0.2.2/imp1.xcframework.zip)
2. Unzip & Drag **imp1.xcframework** into your iOS app.
3. Use the `prove()`, `parallel_prove()`, and `verify()` functions from the framework’s public interface. See [`PublicApi.h`](./ios/imp1/imp1/PublicApi.h) for function definitions, usage comments, and required types.
4. More details in the platform-specific [README](./ios/README.md)

### Android

1. [Download the aar](https://github.com/ingonyama-zk/imp1/releases/download/v0.2.2/imp1-0.2.2.aar)
2. Drag **imp1-0.2.2.aar** into your Android app.
3. Use the `prove()`, `parallel_prove()`, and `verify()` functions from the library’s native bridge. See [`NativeBridge.kt`](./android/imp1/app/src/main/java/com/ingonyama/imp1/NativeBridge.kt) for function definitions, usage comments, and required types.
4. More details in the platform-specific [README](./android/README.md)
